Z geometry

Definition

Z geometry is a descriptor used in organic chemistry to indicate that the highest priority substituents on each carbon of a double bond are on the same side. This nomenclature is part of the E,Z designation system for determining alkene stereochemistry based on Cahn-Ingold-Prelog priority rules.
